Natural phenols are a class of molecules found in abundance in plants. Many common foods contain rich sources of polyphenols which have antioxidant properties only in test tube studies. As interpreted by the Linus Pauling Institute, dietary polyphenols have little or no direct antioxidant food value following digestion. [7]
The main source of polyphenols is dietary, since they are found in a wide array of phytochemical-bearing foods.For example, honey; most legumes; fruits such as apples, blackberries, blueberries, cantaloupe, pomegranate, cherries, cranberries, grapes, pears, plums, raspberries, aronia berries, and strawberries (berries in general have high polyphenol content [5]) and vegetables such as broccoli ...
Metals catalyse oxidation. Some fatty foods such as olive oil are partially protected from oxidation by their natural content of antioxidants. Fatty foods are sensitive to photooxidation, [17] which forms hydroperoxides by oxidizing unsaturated fatty acids and ester. [18]
Carotenoid-dense foods should be consumed skin-on, as the most significant quantities are found in the outer casing. These colorful antioxidants support eye health and have been shown to guard ...

Natural polyphenols have long been proposed as renewable precursors to produce plastics or resins by polymerization with formaldehyde, [33] as well as adhesives for particleboards. [34] The aims are generally to make use of plant residues from grape, olive (called pomaces ), or pecan shells left after processing.
Elderberries are tart, dark purple berries from the Sambucus nigra tree that are packed with vitamins, minerals and antioxidants. They’ve been used for centuries as a natural remedy for colds ...
Natural phenols are reactive species toward oxidation, notably the complex mixture of phenolics, found in food for example, can undergo autoxidation during the ageing process. Simple natural phenols can lead to the formation of B type proanthocyanidins in wines [ 17 ] or in model solutions.
